Abstract

Abstract

In order to investigate the behavior of Q460 high strength steel welded box columns under axial compression,numerical analysis was performed with both numerical integration method(NIM)and finite element method(FEM).The numerical models were based on the previous experiments conducted by authors.The measured initial geometric imperfections and simplified distributions of residual stresses were taken into account in the numerical models.The predicted results obtained through NIM and FEM showed a good agreement with each other.The comparison of test results with numerical results was presented for verifying the NIM program.It was demonstrated that both NIM and FEM,which took initial imperfections into account,could predict reliable results of the behavior of Q460 high strength steel welded box columns under axial compression.Moreover,the accuracy of the simplified distributions of residual stresses was verified by comparing the FEM results considering measured distributions with FEM results considering simplified distributions.
